[15/08/2011] Researchers in the Hotchkiss Brain Institute (HBI) at the University of Calgary's Faculty of Medicine have uncovered a mechanism by which stress increases food drive in rats. This new discovery could provide important insight into why stress is thought to be one of the underlying contributors to obesity.Uncovering Mechanism: Link Between Stress and Appetite - Read more

[08/06/2011] The consumption of fat food causes more insulin to be released by the pancreas. This triggers a signalling cascade in special nerve cells in the brain, in which the enzyme P13-kinase plays an important role. Over the course of several intermediary steps, the insulin inhibits the transmission of nerve impulses in such a way that the feeling of satiety is suppressed and energy expenditure reduced.

[20/04/2011] The brain’s hypothalamus plays a key role in obesity and type 2 diabetes. Nerve cells in the hypothalamus detect nutrients and hormones circulating in the blood and then coordinate a complex series of behavioural and physiological responses to maintain a balance between calories eaten and calories burned. Obesity and diabetes can result when this regulatory mechanism goes awry.Research: Link Between Brain Molecule, Obesity and Diabetes - Read more

[15/12/2010] A team of scientists now showed that a lifelong diet with fat and carbohydrates reduced the life expectancy of mice by 33 percent. By contrast, high fat feeding with a high protein but low in carbohydrates reduced the life expectancy of rodents simply by seven percent.
